llw inven- 3. In securing'rim 7 to the plates 3, each y offtliese parts is preferably provided with lthe lateraledges of the rim.

dove-tails, as shown in Figs. l, 2 and 3, the dove-tails on the outer edge of the plates 3 being indicated by the reference 8 and the dove-tails on the riin 7 being indicated by the reference 9. s i

Fig. l shows the rim 7 and the side-plates 3 properly assembled with the dovetti-ils on these parts holding the parts in proper relative positions. Figs. 2 and 3 illustrate the procedure in securing these parts together. The dove-tails 9 on the rim 7 are initially made ot a length slightly less than the thickness of the side-plates 3. Therefore, when the parts are assembled, as shown in Fig. 2, the non-adjacent faces of the side-plates 3 stand slightly beyond the ends of the dovetails 9. These parts are then clamped together in the clamps of an electric Welding machine and While a welding current is being passed through them, they are subjected to high pressure. As a result ot this operl ation, the faces of the disks or side-plates 3 25` become flush with the edges of the rirn 7, that is, with the ends of the dove-tails 9. In this Way, these parts are secured together so firmlyA that e. very strong structure'is produccdywhich consists of few parts readily assembled,.which can be manufactured at low cost and which, in addition to its great strength, possesses the requisite amount of elasticity.

Referring now to Figs. 5, 6 and 7, alternative methods which may be employed in securing the side-plates and rim togetherr will be described. In Fig. 5 the underside of the rim 7 is shown as provided with grooves adjacent to its lateral edges, each of thesey grooves having one Wall disposed in the general plane of the Wheel, and the other Wall inclined as shown at l0 in Fig. 5. The

side-plates 3 are provided. with inclined or beveled peripheral edges shaped to coact with these grooves in the rim 7. `With the p'arts so constructed, the side-plates and rim are tassernbled in proper relative positions and then the rim is shrunk so that the outer ldges 'of the side-plates enter the grooves im Fig. G shows a construction quite similar to that illustrated in Fig. 5, the only difference being that the grooves in the rim are differently shaped and the edges il of the side-plates are formed to coact with these grooves. It will be seen that lboth walls oi' the grooves in the rim lie in the vplane of the Wheel In Fig.' 7, a construction somewhat similar to that shown in the Figs. 5 and 6 is illustrated. I-Iere the rim 7 is provided with grooves at the lateral.edges,v one Wall of which lies in the plane of the wheel and the other Wall of 'which is transverse to that plane. The outer edges of the side-plates to these grooves except side-plates toward. the outer sides thereof are beveled as shown at 12; `With this construction, the parts are joined by peening rather than by shrinking. It will be seen that the metal of the rim 7 is upset as shown at 13 so as to overlie that edge of the sideplat-e 3 Whiehiis beveled at l2. In the three constructions illustrated in Figs. 5, .6 and 7 it Will be seen that an interlock is effected between the side-plates 3 and the rim 7 such that the side-plates cannot be moved one away from the other in such a Way as would cause disengagement of one or both of the side-plates from the rim 7.

The method illustrated in any one of Figs. 5, (5 and 7 may, if desired, be combined With that shown in Fig. 3. That is, the dove-tail construction shown in Fig. 3 may be employed and the underside of each dove-tail projection on the rim 7 may be grooved as shown in Figs. 5, 6 or 7; also those portions 'i of the edge of the side-plate 3 which lie between ,adjacent dove-tails on the side-plate may be formed as shown in Figs. 5, 6 or 7. The structure produced in this Way would possess great strength by reason of the enfi-l ployment of the dove-tail construction and this strength would be augmented by the i edges of ,said plates and rim being correvspondingly notched and in'terloclred to form dove-tailed joints, and Welded ltogether to form an inseparable structure, substantially as set forth. i

2. A vehicle Wheel comprising a metallic nib, two side plates of pressed shectmietal secured thereon' and a sheet metal riin, said rim and sido plates being interlooked at their edges and Welded together to form an inseparable structure, and said side plates being dished so that they diverge toward., -their outer edges, and provided With a stiffening head in the diver-ging portion, substantially as set forth.
